Share this:

The Office of Statewide Health Planning and Development (OSHPD) released its fourth Coronary Artery Bypass Graft Surgery Report (CABG). This CABG Report measures the performance of all 284 cardiac surgeons who performed 32,586 isolated heart bypass surgeries during 2005 and 2006. Quality ratings are also provided for 121 state-licensed hospitals where the procedures were performed.

Based on the clinical data, in 2006 the overall CABG mortality rate was 2.22%, a 28% reduction from the 3.08% overall rate in 2005. For the 2005-2006 period, the overall mortality rate was 2.65%, a 14% reduction compared to the operative mortality rate of 3.08% recorded in the 2003-2004 period. This reduction in mortality means that 379 fewer lives were lost in 2005-2006 compared to the 2003-2004 period. This report also includes the 2006 hospital ratings for use of the internal mammary artery, an important evidence-based indicator of surgery quality.
